Took him just under 3 years for the first one, but a good chunk of that time was spent on the admittedly interesting kimba tangent video. Given he hasn't seemed to have even properly started on the second other than potentially a very brief bullet point list of scenes he wants to go over, I'd say late 2027 at the earliest, that's if he starts soon. Imagine the virtually free algorithm boost he'd have if he was remotely competent and even putting this on the backburner, took a break from it for the rest of 2022, and then worked on it in his spare time through 2023 and 2024 and had it ready for the Mufasa movie.
